Abstract

Tetranitrodimerglycoluril (TNDGU) is a newly developed insensitive energetic material. Its solubility in methanol, propanone, ethyl ethanoate, and ethanenitrile between 293.15 K and 313.15 K at atmospheric pressure was investigated by the gravimetric method. The order of the solubility of TNDGU is ethanenitrile > ethyl ethanoate ≈ propanone > methanol. The solubility of TNDGU increased with an increase of temperature. The enthalpy of dissolution in each solvent was also calculated according to a modified van't Hoff equation; the values are 25.18 kJ·mol^-1 for methanol, 41.26 kJ·mol^-1 for propanone, 34.70 kJ·mol^-1 for ethyl ethanoate, and 36.33 kJ·mol^-1 for ethanenitrile, respectively.
